Octadecenylsuccinic Anhydride CAS 28777-98-2
Octadecenylsuccinic Anhydride (ODSA) ni ibikoresho byoroheje bikoreshwa cyane mu nganda zoroheje. Mu nganda zikora impapuro, ikoreshwa nk'ikintu gipima ubunini butagira aho bubogamiye kugira ngo yongere cyane imikorere idapfa amazi, imbaraga zo gukurura, kudashwanyagurika, umweru, kudahita kw'impapuro no kunoza ibidukikije by'ubutabire mu nganda zikora impapuro. Ubusanzwe, inzira ikoreshwa ni ugukora isomeri ya alpha olefins hanyuma igakora na maleic anhydride kugira ngo ikoreshwe.

1. Octadecenyl succinic anhydride (ODSA) ni igikoresho gipima cyane ingano, gikoreshwa cyane cyane mu gupima ingano y’impapuro mu nganda zikora impapuro. Igizwe n’agatsiko ka olefin kadafite ingano gahujwe na succinic anhydride, kandi akenshi gakorwa mu ntambwe ebyiri: icya mbere, unsaturated straight-chain cyangwa branched olefins zishyirwa muri isomer binyuze mu kwimura double bond; hanyuma, imvange ya olefin ya isomerike ihura na maleic anhydride, kandi ibikoresho fatizo bya ASA biboneka binyuze mu kongeramo reaction no gutunganya bihuye. ASA ni amazi ku bushyuhe bw’icyumba kandi ifite uburyo bwiza bwo kubika, ibi biterwa n’ingaruka zayo zo gufunga no gufunga, bigerwaho binyuze mu kugenzura charge no guhuza emulsifiers, stabilizers, promoters na retention aids. Kugira ngo hongerwe retention ya ASA ku migozi, quaternary ammonium cationic starch, polyacrylamide (retention aid), methylene dithiocyanate (preservative) na cationic polymers zirimo polyamines akenshi zikoreshwa nk’ibikoresho bishyigikira.
2. Byongeye kandi, octadecenyl succinic anhydride (ODSA) ikoreshwa kandi nk'ikintu gikoreshwa mu gukora imiti kandi igira uruhare runini mu gukora imiti. Imiterere yayo ya shimi irakora kandi ishobora kugira uruhare mu bikorwa bitandukanye bya shimi kugira ngo ikore indi miti, ibi bigatuma ikoreshwa cyane mu nganda zitandukanye2.
3. Muri make, anhydride ya octadecenyl succinic ntabwo ikoreshwa gusa nk'ikintu gipima ingano mu nganda zikora impapuro, ahubwo ikoreshwa kandi nk'ikintu cy'ingenzi mu nganda zikora imiti, igaragaza ikoreshwa ryayo ryagutse n'akamaro kayo mu nganda zikora imiti.
